Abstract
The invention refers to a hard-soldered (brazed) flat tube evaporator with a dual flow (double flow) and one row in the air flow direction of aluminum or an aluminum alloy for a motor vehicle air conditioning equipment in which on the inlet side a distributor of the refrigerant to the inlets of individual flat tubes or preferably groups thereof is provided and the flat tubes are extruded multi-chamber tubes between which zig zag fins are internested in a sandwich fashion. According to the invention, it is provided that the structural depth of the evaporator is at most 50 mm.
Claims32
A dual flow flat tube evaporator having one row in the air flow direction for a motor vehicle air conditioning equipment, comprising:
- a plurality of multi-chamber flat tubes;
- a distributor of a refrigerant to inlets of individual flat tubes or to groups of the same;
- zig zag fins internested in a sandwich fashion between the flat tubes,
- whereas the interspace occupied by a zig zag fin between two adjacent flat tubes is at least 5 mm and at most 9 mm;
- and
- the evaporator having a structural depth of at least 25 mm and at most 50 mm.
A flat tube evaporator, comprising:
- a plurality of adjacent flat tubes aligned substantially parallel with one another, wherein the depth of the flat tubes is at least approximately 25 mm and not more than approximately 50 mm, and the spacing between adjacent flat tubes is at least approximately 5 mm and not more than approximately 9 mm.
A method for conditioning air, comprising:
- distributing a refrigerant through a plurality of aligned flat tubes separated from one another by at least approximately 5 mm and not more than approximately 9 mm;
- and
- distributing a stream of air across zig zag fins placed between adjacent flat tubes, the distance across the zig zag fins being at least approximately 25 mm and not more than approximately 50 mm.
